Gabelich drove a split window 1960 era Volkswagen delivery van for Vermillion's Drug store in his younger days. He lived with his parents in the Bixby Knolls area of Long Beach, California during this time. He later went to work for North American Aviation which became North American Rockwell after a 1967 merger with Rockwell-Standard. Gabelich started in the mail room and stayed for nine years in various positions from staff assistant before becoming a part-time test subject for Project Apollo in the years 1968 and 1969. Gabelich served as an Apollo test astronaut in 1968-1969 as stated on the plaque his family dedicated to him in 2001. Unlike the actual astronauts, he was not flying the capsules, but testing their long-term viability in weightless conditions, their tolerance and performance under conditions of extreme lateral forces and, though they seldom spoke of it on televised moon shots, the toilet facilities. Gabelich was Mercury Seven astronaut Wally Schirra's exact size and he did a lot of space checkout for him and testing of capsules and equipment before they were man-rated for operational use. Project Mercury ended in the early 1960s and Wally Schirra went on to become commander of Apollo 7.
Gabelich broke the LSR by achieving average speeds of over a flying mile and over a flying kilometer. The thrust used during this attempt was between 13,000 pounds and 15,000 pounds. A top speed of approximately was momentarily attained during one run. The FIA rules dictate that a land speed mark is recognized only after two runs through the FIA measured kilometer and mile courses. The two corresponding speeds are then averaged for the official time and speed. Additionally both runs must be made within one hour. Gabelich averaged on his first run and on his second run for an average speed of establishing a new kilometer FIA LSR. The mile FIA LSR was the first exceeding and remained unbeaten until 1983, when Richard Noble broke it driving Thrust 2. The faster kilometer FIA LSR remained unbroken for 27 years when ThrustSSC went supersonic in 1997.
Racing career
In 1969 Gabelich established a quarter mile Drag boat record of This is not the same as the Union Internationale MotonautiqueWater Speed Record in which Donald Campbell broke on 23 July 1955 in the Bluebird K7. Gabelich was seriously injured in the crash of an experimental 4 wheel driveFunny Car in 1972 that careened out of control at during a quarter mile run almost severing his left forearm and broke his left leg so severely that more than a year later he still wore a cast. This incident ended his racing career and he never raced again, concentrating instead on a new supersonic vehicle.
After racing
In the early 1980s he established the "Rocketman Corporation" with Tom Daniel. The objective was to design and build a vehicle capable of reaching speeds in the range. This conceptual vehicle was named "American Way" but the project was cut short by his untimely death in January 1984 in a motorcycle crash. Gabelich was part of the cast in the 1977 movie Joyride to nowhere and he made a documentary, One Second from Eternity: The History of the Land Speed Record in 1971. Gabelich and his family appeared on Family Feud with Richard Dawson, where he presented the key to the city of Long Beach, California to Dawson. In 2008 Gabelich was inducted into the Long Beach Motorsports Walk of Fame in front of the Convention Center on Pine Avenue. He was represented at the ceremony by his wife Rae, a Long Beach City Councilwoman who retired in 2012 after eight years of service. He was inducted into the Motorsports Hall of Fame of America in 2016.
